SAFETY RAZOR.

Specification'of Letters Patent.

Patented Mar. 21, 19.22.

Application filed November 15, 1921. Serial No. 515,315.

. To all whom it may concern Be it known that I, WlLLIAM A. BARRY, a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.

This invention relates to improvements in safety razors, and more particularly to a.

type of razor having an adjustable handle.

An object of the invention is to provide a suitable safety razor which will be inexpensive to manufacture, and which will be highly efiicient in use.

Another object of the invention is to provide a suitable'safety razor which will combine the several parts to produce a mycrometric adjustment, thereby securing a wider range of movement of the adjusting means while securing a minute adjustment of the cutting edge for shaving.

A further object of the invention is to provide a suitable safety razor with an adjustable handle, which will be so constructed that it will be easily cleaned, and will permit of any adjustment angularly with respect to the face when being operated.

Other objects will appear as the description proceeds.

In the accompanying drawings which constitute a part of my application Figure 1 is an end elevation of the preferred form of my razor assembled.

Fig. 2 is atop plan view of the front plate.

Fig. 3 is bottom view of the front plate.

Fig. 4 is an end elevation of the front plate.

Fig. 5 is a top plan view of the guard plate.

Fig. 6 is a bottom view of the guard plate.

Fig. 7 is an end elevation of a modification of the razor.

Fig. 12 is a vertical longitudinal section of the second modification.

Fig. 13 is a bottom plan view of the front plate of the second modification.

Fig. 14 is an end elevation of the guard plate of the second modification.

Like characters of reference are used throughout the several views and the following specification to designate correspondlng parts.

The three modifications of my improved safety razor will be described separately covering Figures 1 to 6; Figures 7 to 10 and Figures 11 to 14, respectively.

In the first modification of my improved safety razor, the front plate '1 is an approximate arc (with a definite radius comparative to the outside radius of a half dollar) and has its opposite edges 2 formed very thin and sharp to avoid any break where it contacts with the outward edges of the double edged blades, or outward ed es of one blade 'if a different "style single-double edged blade is used. This is for the purpose of allowing the flesh to contact with the smooth surface of the back of the front plate and the guard teeth 6, excepting a two thousandth of an 6 inch variation of the guard teeth 6 from the front plate, and is equi-distant from tlie ends of the plate. The sockets 4 are formed in the inner face of the front plate,

and are spaced on either side of the stud 3, and midway of the ends of the plate. The front plate 1 is made ri id, remote from-its thin sharp edges and wi ll not bend or give.

The guard member-5 is provided with the oppositely disposed teeth 6, which are approximately two thousandths of an inch less in thickness than the portion of the guard member adjacent the inner ends of the teeth. The edges of the front plate 1, Figure 2 will extend one sixteenth of an inch and over or past where the -guard teeth 6 begin or are formed on the guard member, the-over distance being governed by the clamping process of the handle. The guard member 5 is curved approximately the same radius as the front plate 1 measuring from the outer end of the guard teeth 6 to where the break or flat surface sets in, where the back of the radius of member 5 is discontinued throughend to end. This flat surface however is the same thickness as the base of the guard teeth, I,

excepting the changed thickness heretofore mentioned of the teeth 6"the two thousandth of an inch thinner as explained. The discontinuing of the radius of the guard member 5 on the back permits ofthe retracting of the blade 7, when the two lates, figures 1 and 6 are clamped together by the handle 8. An opening 9 is formed in the center of the guard member 5, which is adapted to receive the threaded stud 3 on the plate 1. Positionedat either side of the opening 9 in the guard-member 5 are two short studs or alinement posts 11 which are adapted to seat in the sockets 4, member 3 or in the inner face of the front plate 1, to keep the blade 7 in position longitudinally, and also serve to hold the blade 7 while the guard plate member 5 is bein clamped by the handle 8 and caused to sli e over the blade 7, which serves to bend more and more the blade 7 as the handle 8 is clamped tighter, thereby drawing the cutting edges 7 further back towards the edge of the front plate 2, which produces a light or heavy shave to suit the operation.

To assemble the razor, it is only necessary to hold the guard member as indicated in Figure 1, place the blade 7 thereon, after which place the front plate 'on top .of the" blade and insert thethreaded stud 3 of the plate 1 through the guard hole 9, member 5 and the center hold of blade 7 and screw the handle 8 on to the stud 3, member 3 or front plate, until the blade is retracted the desire amount to provide the desired shave.

The angle of the blade 7 with respect tothe guard member 5 and the front plate 1 will alwa s be the same when contacting with the esh,.but the adjustment made by turning the handle 8, will only vary the blade 7 forwards orbackwards to provide a li ht or heavy cutting of the hair.

e second modification of my razor, illustrated in Figures 7 to 10 inclusive, is quite similar to the preferred form illustrated. in Figures 1 to 6 inclusive, with the following exceptions.

The front plate 1 is provided with a central threaded opening 10 and with the studs 12 at either side of said opening. The guard plate 5 of this type of razor is provided with three alined openings 13, and the upper longitudinal surface of the plate is flattened as at 14 to form the bearing edges or shoulders 15 to form a rocking chair effect when the handle is tightened down drawing the two plates tighter together.

With this type of razor, there is a positioning of the blade due to the shoulders 15 hearing against the blade, and also an angular adjustment of the edge of the blade,

' due to said shoulders.

The third modification of my improved razor is illustrated in Figures 11 to 14 inclusive, and combines some of the features of the first two types, with these additional features. The front late 1 is now provided with a central t readed stud 16 and with the notches or sockets 17 at either side of the stud and midway the ends of said plate 1. The front plate 1 is also provided with the ears 18 formed at the opposite ends, which are adapted to engage and seat in the notched out sockets or hearing or guiding grooves 19 in the opposite ends of the guard member 5.

The guard member 5 is also provided with a central opening 20, and a pair of studs 21 spaced midway between said opening and the ends of the plate. .These studs while holding an apertured flexible blade in pos1- tion are also adapted when the limit of adjustment has been reached to seat in the openings or sockets 17. Therears 18 serve to limit the positioning of the blades 22, should two small narrow blades be used with the razor instead of one wide blade.

The handle 23 is of the ball bearing adjustable type, and is provided with the barrel portion 24 which is open at both ends, and an inner tube 25 which is slidable in the barrel 24, and. which is closed at its bottom end. There is a screw threaded opening in the center of the bottom of the tube 25, into which the screw is adapted to be threaded,

said screw being carried by the knob 26, the turning of which adjusts the handle until it is tightly assembled.

The upper end (that is the end which contacts with the ball) is split in order to receive the ball 27 which carries the socket 28 or threaded stud 28, which engages the front plate and the guard plates to hold the razor in operative position.

It will be understood that many minor changes in detail of construction may be resorted to and that other means maybe applied to operate the same principles in volved without departing from the spirit of the invention.

To assemble the razor, it is only necessary to place the blade or blades on the front plate, then lace the guard plate thereon, and attach the liandle, and tighten until the desired angle and edge is arrived at to suit the operator.

The. accuracy and precision of measurement together with the carefully worked out and constructed parts of this razor combine to make it as near eific'ient as possible.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

. 1. A safety razor comprising a front plate, a guard plate, spaced blade positioning studs carried by said guard plate and formed-intermediate the center and ends of said plate, the front plate having a depending threaded stud at its center and being provided with spaced sockets intermediate the threaded stud and the ends of said plate,

depending ears formed at the ends of said tral aperture and guiding recesses at its opposite ends to receive said ears.

2. A safety razor comprising a front plate having the approximate curvature of the radius of a silver half dollar of the coinage of the United States of America, a guard plate -of approximately the same radius as the front plate, a blade positioned between said plates, and means for simultaneously changing the angle of the blade and the relative position of the edge with respect to the outer edges of the guard plate.

3. A safety razor comprising a front plate having the approximate curvature of the radius or a silver half dollar of the coinage of the United States of America, a toothed guard plate of approximately the same radius as the front plate, a blade positioned between said plates, and spaced longitudinally extending curved shoulders formed on said guard plate by slightly reducing the upper faces of-the guard teeth for gradually changing the angle of said blade, whereby the angle of the blade edge can be slightly adjusted with respect to the guard teeth.

4. A safety razor comprising a front plate having the approximate curvature of the radius of a silver half dollar of the coinage of the United States of America, a guard plate of approximately the same radius as the front plate, a blade positioned between said plates, a handle, the opposite edges of said front plate terminating in thin flexible portions, whereby the said portions will gradually give to prevent breaking of the blade upon the tightening of the handle.

5. A safety razor comprising a' front plate having a pronounced curvature, a guard plate of approximately the same curvature as the front plate, teeth formed at the opposite edges of said last mentioned plate, a

blade positioned between said plates, thecurvature of said plates being so pronounced that upon adjustment, the edges of said blade will be shifted forwardly along the guard teeth and'closer to the saine.

6. A safety razor comprising a front plate, a guard plate, a blade positioned between said plates, reduced teeth at the opposite edges of said guard plate, the opposite edges of said front plate terminating in thin flexible portions, whereby there will be a larger range of movement of the adjusting means with a slight adjustment of the cutting edge.

In testimony whereof I affix my si nature.
